Problem Statement

Write a C program to implement a function that rotates an array left by k positions using pointer arithmetic and slicing.

Input Format

First line contains n and k. Second line contains n array elements.

Output Format

Print the rotated array elements separated by spaces.

Constraints

1 <= n <= 100, 0 <= k <= 100

Sample Input

5 2
1 2 3 4 5

Sample Output

3 4 5 1 2

Explanation

Use pointer offsets to shift sections of the array efficiently.

Starter Code

#include <stdio.h>

int main() {
    int n, k;
    if (scanf("%d %d", &n, &k) == 2) {
        int arr[100];
        for (int i = 0; i < n; i++) {
            scanf("%d", &arr[i]);
        }
        // Write your code here for pointer array rotation challenge
    }
    return 0;
}
